Application filed October 559. i925. aerial.

This invention relates to a vaporizing inhaler tor use in the prevention and treat-- ment ojii certain diseases of the respiratory oru'ans. (lu cotl the objects of the invention to pro vide a simple and inexpensive device by means ot which any medicated solution oil or aqueous) can be converted into a line vapor suitable for inhalation and containing all the ingredientso'li the solution. A turther object to provide an instruuwnt by means ot which the 'aporizinn' oi the liquid may be cli'ccted by the simple act of inhalation or breathing through the nose or mouth without the danger of any portion or part ot' said solutioi'i reaching the nose or throat except in a highly subdivided 'vaporous or ous term. l urihcr objects of the invention are to provide a vaporizing inhaler ot the character referred to which is small, compact and easy to sterilize and to use, which has no movable or adjustable parts liable to get out or order and which can be inaiuitacturcd at a very low cost.

iE-lt further object of the invention is to provide a device in which aininiinui'i'i quantity ot the medicine is used and in which a greater proportion of that used actually reaches the portions of the respiratory tract :io needing treatment.

it further object to provide a device by which a. suitable medicant may be applied to the miurous nieu'ibranes in actual substance and in such a manner that the delicate tissue will not be irritated.

l i ith the above and other objects in View the invention may be said to comprise the instrinnent as illustrated in the accompany inp; drawings hereinafter described and particularly set forth in the appended claim together with such variations and 1nodilications thereof as will be apparent to one skilled in the art to which the invention appertains.

lteterence should be had to the accompanying drawings forming a partoili this specification in which Fig. 1 is a vertical section showing an instrument embodying the invention placed in an ordinary glass tumbler which serves as a receptacle for the liquid to be vaporized by the act of inhalation; Fig. 2 is a section taken on line 2-% 0t liig. 1; Fig. 3 is a section taken on line 3;:l of Fig. 1; Fig. i is a side eievat in partially in. section showing a modified :torm

oil? the invention; Fig. 5 is a section on line 5-5 01'' Fig. l.

As shown in liigs. 11. 2 and S the vaporizing inhaler forming the subject matter oi? the present invention is preferably torntled of glass tubing and has a tulmlar body portion jl open at the lower end and provided. with an outwardly tlarinu' base portion El 'l'ormii'nr a stable suppint tor the instrument when it is stood on end. Around the base portion 2 there are oircuniterentially spaced shallow indentations 3 through which air and liquid may pass into the interior of the hollow body. The upper end oi the hollow body portion 1 is somewhat enlarged to prorule on expansion chamber and extending: upwardly from the upper end of the body 1 there is a tulmlar cnteusioi'i'o which is ot a diameter considerably than, the d ia1ueter of the tubular portion 1. and lower portions (l and T of the tulnilar extension 5 are substantially in axial a f inincnt with tubular body portion 1, and intermediate the portions 6 and 'i the tube 5 is bent laterally at 8 to provide a tortuous passage for the vapor d rawn upward lyiltroin the body portion 1. The u )pei.' end of the tubular extension 5 has an enlargement 9 forming an expansion chamber and at the top of the enlarged portion 9 there is a relatively slnall outlet 10 through which the vapors may be drawn into the hose or mouth ot the person using the instrument. ht its lower end the tubular extension 5 has a. portion ll extending down. into the ciqiansiou chamber 4t at the uip ier end of the body portion l for a purpose to be hereinafter ea:- plained.

l Vhen the inhaler is used it is placed in a suitable receptacle with the base E2 resting; upon the bottom oil. the receptacle and a small quantity oi? the liquid to be va iorized and inhaled is placed. in the receptacle. The person takiiug the treatment will place the mouth or nose to the outlet 10 ot the inhaler and inhale through the vaporizer. The reduction ot pressure within the tubular body 1 will cause the liquid in the bottom of the container to tlow through the openings 3 into the interior of the tubular body 1 until practically all oi the liquid in the container is Within the base portion 2 of the inhaler. At the same time air will be flowing rapidly through the openings 8 and this air will violently agitate the small llhe upper [ill Pill

the vaporizer is so constructed that the larger drops of liquid will be deposited upon the walls thereof and only very minute particles of liquid can pass with the air through the outlet nozzle 10. The air in passing upwardly through the tubular body 1 passes into the expansion chamber 4 where the Velocity is slowed'down and larger particles of liquid carried in the air stream Will be thrown against the wall of the body or against the outer wall of the portion 11 of the discharge tube which extends down into the expansion chamber l. While passing'through the bent portion 8 of the tube 5, any of the larger particles of liquid will be dashed against the walls of the tube and in passing through the expansion chamber 9, the velocity will be again slowed down and any of the larger particles of liquid which have been carried up in the air stream will be deposited upon the walls of the chamber 9.

The inhaler as shown herein is designed to be used with an ordinary glass tumbler and the height of the body portion 1 is such that when the inhaler is placed in the tumbler the top of the body portion 1 will be but slightly above the top of the tumbler. This enables the person using the inhaler to grasp the top of-the tumbler with the tube 5 extending between two fingers which rest upon the top of the expansion chamber l and hold the body portion 1 with the base 2 thereof tightly against the bottom of the tumbler. lVith a standard tumbler the amount of liquid used is preferably about one dram Which is just about sufficient to fill the bottom of the tumbler to a point slightly above the top of the inlet openings 3. As shown herein the inlet openings 3 are placed one diametrically opposite the other so that the air currents tend to force the liquid to the center and the liquid so forced'inwardly will be continually falling back into the air stream so that a very effective mixing action is obtained and the air will become thoroughly saturated with vapor.

In modifications shown in Figs. -land 5 the inhaler has a tubular body 1, llaring base 2 and inlet openings 3" identical with the modification first described. The tube 5", however, opens directly into the upper end of the body portion 1* the extension 11 being omitted. Otherwise the modified form shown in Figs. 4 and F is identical with that shown in Figs. 1, 2 and 3.

Having described my invention what I claim is:

A vaporizing inhaler comprising a tubular body portion having an open outwardly flared lower end portion :nlapted to rest upon the bottom of a container in which there is a small quantity of liquid the lower edge or" said body portion having circum ferentially spaced indentations 'ljorming passages permitting air and liquid to llow along the bottom of the container to the interior. of the body portion, said body portion having an enlargement at its upper end forming an expansion chamber, and a tube of a diameter relatively small with respect to the body portion connected to the enlarged upper end of the body portion. said tube having a restricted discharge opening and an enlarged portion i'orming an expansion chamber adjacent the discharge opening, the discharge opening and enlargement being substantially vertically above said body portion, said tube being laterally bent between its enlarged portion and the body portion, to thereby term a tortuous baflle passage.

In testimony whereof, I hereunto allix my signature.

FRANK C. DORMENT.
